FOLDING BOX.

Specification of Letters Patent.

Patented Sept. 19, 1911.

To all whom it may concern Be it known that I, JOHN G. REBER, a citizenof the United States, residing at Chicago, in the county of 'Cook andState of Illinois, have invented certain new and useful Improvements inFolding Boxes, of which the following is a specification.

My invention relates to folding boxes made of paper board or thelike,and the general object thereof is to provide a simple and efficient boxof this character, possessing features of advantage and utility whichwill be apparent from the description hereinafter given. 7

My present invention is an improvement upon that described and claimedin an application for patent filed by me on March 19, 1906, Serial No.306,854, in which form of box I employed flexible strips of wood or thelike at the top edges of two of the opposite sides for the purpose ofnot only strengthening such sides but also of holding the box in itserect or assembled condition. My present invention pertains moreparticularly to the means for and manner of holding or securing thesestrips to the box and also relates to certain features of boxconstruction to cooperate with said strips.

In the drawings, Figure 1 is a plan View of a blank from which theparticular box herein illustrated, known as a suit box, is formed; Fig.2 a perspective of one corner of the box showing. method of folding;Fig. 3 an enlarged sectional elevation on the line 3-3 of Fig. 4; Fig. 4a perspective of the box in its assembled or erect form; Figf 5 aperspective of one end of the box with its flexible strip removed; Fig.6 a section on the line 66 of Fig. 3; Fig. 7 an elevation of a portionof one end of the box; Fig. 8 a plan view of one end of a blank ofmodified form; Fig. 9 a perspective of one end of abox made fromthemodified form of blank illustrated in Fig. 8; Fig. 10 a section onthe line l0-10 of F ig. 9; and Fig. 11a perspective on a somewhat largerscale than in Fig. 9 illustrating one end of suchmodified form of boxbut with its flexible strip-removed.

My invention is applicable to different forms and types of boxes, suchas hat boxes, suit boxes and the like and, although in the presentinstance I have shown my invention in connection with the particularform or type of box known as a suit box, yet it will be understood thatI do not intend to limit myself to such special form of box,

particularly as the proportions of the box may be obviously changed toproduce a great variety of boxes intended for different specialpurposes.

Referring'to the present embodiment of my invention; which is in theform of the well-known suit box, the blank from which such box is formedcomprises a rectangular bottom A, two opposite side walls B, two endwalls C 0, all of which are hinged to the bottom A, and also cornerfolds I) and E. These corner folds are substantially triangular, thesame being arranged in four pairs at the four corners of the box, of

which the folds D are hinged to the ends 1 walls C, and as a matter ofconvenience in description, I prefer to call theformer the side wallsand the latter the end walls, al though they all may be considered sidewalls.

To the outer edges of the end walls G of the box are hinged extensionsor flaps which are hinged upon each other and adapted to be folded overupon or wrapped around strips F of flexible material, such as thinstrips of wood or wood veneer, such folding being done in the particularmanner hereinafter explained. As shown the innermost flaps or extensions0 are continuous or entire but by preference, thc'outermost ones only ofthese flaps are severed, the same being transversely out along the twolines 0 so as to form the end portions 0 and the central or intermediateportions or extensions 0?. As shown in Fig. 1, the lines o are obliquefor the purpose of cutting the outer corners of the flaps a on a bias,thereby forming on the inner adjacent corners of the extensionsc thetongues or points having the'ofli'c'e or function hereinafter ex- 7plained.

' In pra'etlce, the strips F which are flexible and afford a torsionalstrain. or pressure when twisted, are folded or wrapped within theextensions or flaps, the extensions 0 being tucked behind the stripswith their outer faces lying against the inner faces of the end walls ofthe box. The intermediate or short flaps 0 are merely folded over thestrips and positioned flat against the inner faces of the end walls ofthe box as shown in Fig. 4., instead of being folded underneath andaround. the strips, as is the case with the .extensions 0. Theintermediate extensions are secured to the end walls of the box in anysuitable manner, as for. -instance by means of a staple G passingthrough such end walls and through the extensions 0 as clearly indicatedin Fig. 4. b v

The box as thus far described represents the construction as produced atthe factory,

the box being shipped. to the customer or by the customer or user to putthe box to use the same is brought to erect form by merely raising theend walls and folding them together toward each other and then liftingand slightly twisting the ends of thestrips in order to permitsuch'strips to slip over the upper edges of the corner folds and to taketheir position on the inner sides or faces thereof. In. this lifting ofthe strips, the latter are twisted, but owing to the fact that they are.flexible and resilient, the same spring back into normal conditionafter they have been slipped over the upper edges of the corner folds tothereby lock and maintain the box in erect form.

By dividing the outermost flaps or extensions in the manner describedthe. strips are held in proper relationship with the end Walls by meansof theintermediate or central extensions, but at the same time are per-I mitted to properly yield or twist even beyond their middle portions,in the operation of applying them over the corner folds. It will beunderstood that the tongues 0* extend underneath the strips within thelines of the central or intermediate extensions a with the result thatthe extensions thus wrapped around the strips are locked in place sothat in the lifting or twisting'of the strips it is impossible todetachsuch extensions from the strips. In this simple manner the extensionsand strips are held together and at the same time the cutting of thefree corners does not detract from the efliciency of-the' centralextensions but ratherimp'roves the'appearance thereof. The object of thenotches (l in the corner folds D is for the purpose of assembling andlocking the box in erect condition without requiring the strips to beraised as far back as would otherwise be necessary. It will beundersteod that the score lines running longitudinally through thecentral extensions 0 are not'essential but are incidental to theformation .of the score lines which divide the extensions c 0' and onwhich they are hinged.

My invention may be applied to boxes made from different forms'of blankswithout departing from the spirit of my invention. For instance, whilein the box just described both the corner folds D and E were hinged tothe walls of the box, yet if desired only onemember of each pair ofcorner folds maybe so hinged. Such a modified form of box is illustratedin Figs. 8 to 11, wherein the parts similar to those illustrated in theother figures are provided with the same letters of reference butprimed.

As illustrated in Fig. 8 the blank comprises the bottom A,'the sidewalls B B, and the end walls C, of which only one is shown. Each cornerof the box is provided with the corner folds D E hinged on the diagonalline 6, of which the corner folds D are hinged to the ends of the sidewalls B. However, inthis particular instance the corner folds E. are nothinged to the end walls but are separated therefrom by the cute.Moreover, in this modified form'the corner folds E, instead of beingtriangular as in the form hereinbefore described, are'trapezoidal inshape, the same being extended as far as the outer line of theextensions of the end walls. As in the form first described, thismodified form is providedwith end wall extensions 0, 0, but in thisparticular instance both extensions are out and moreover on straightlines 0', there by forming the end portlons or extensions proper marked0 0 and the central or intermediate portions or extensions =0 Inpractice the corner folds E are brou ht inwardly withtheir outer facesresting at upon the inner faces of the end walls and after the stripshave been applied to the flaps or extensions in the same manner aspreviously described, the corner folds E are secured tothe end walls insuitable'manner and in the present instance the parts are so secured bythe same staples or fasteners H which are'employed to fasten the centralextensions c in place, all as clearly indicated in Fig. 9. It is obviousthat the central extensions 0 need not be divided by the longitudinalscore line which is present as an incident in actual practice to theformation of the score line on which the extensions 0, 0 are hinged.Likewise the folds E have two the corner folds E. The box is set up orassembled'to its erect form in the same manner as the first form of boxdescribed.

It will be understood that where my invention is applied to a suit box,where the top and bottom portions are similar, another box portion ofthe same character is provided but difl'ering slightly in size so thatone portion may be readily telescoped into form of suit boxes. Alsowhere my invention is applied to another form of boxsuch as a hat boxany suitable lid or cover, of the same structure as the body portion orotherwise, may be provided.

I claim:

l. A -folding box comprising a bottom, walls hinged thereto, cornerfolds connected with two opposite walls and foldable into the box,flexible strips for the upper edges of the end walls, and separateextensions on each of said end walls, which extensions are wrappedaround the strips; substantially as described.

2. A foldin box comprisin a bottom walls hinged t ereto, corner fol sconnected with two opposite walls and foldable-into the box, flexlblestrips for the upper edges of the end walls, and extensions on said endwalls, which extensions are wrapped around the strips andextendedinwardly on their adjacent edges; substantially as-described.

3. A folding box comprising a bottom,

walls hinged thereto, corner folds connected with two opposite walls andfoldable into the box, flexible strips for the upperedges of the endwalls, and extensions on said end walls, the outermost one of whichextensions is transversely cut in two places, forming two end portionswhich are wrapped around the strip and an intermediate port-ion whichextends over such strip and is secured to its end wall; substantially asdescribed. the other as is the case in the conventional 4. A folding boxcomprising a bottom,

walls hinged thereto, corner folds connected with two opposite wallsand, foldable into the box, flexible strips for the upper edges of theend walls, and extensions on said end walls, the outermost one of whichextensions is transversely out in two places, forming two end port onswhich are wrapped around the strip and an intermediate portion whichextends over such strip and is secured, to its end wall, said endportions being extended inwardly on their adjacent ed as substantiallyas described. v
